Efficient Fixed-Window Array Aggregation Using Prefix Sums
Algorithmic Analysis
The core requirement involves accumulating the totals of every contiguous segment of length $m$ within a sequence of $n$ integers. A straightforward nested loop approach computes each window independently, yielding $O(n \cdot m)$ operations. With constraints reaching $10^6$, this quadratic scaling triggers timeout errors. L ...
